United States Patent TWO-PART DIAPER Christena E. Sires, Palatine, Ill.

Application May 18, 1954, Serial No. 430,553

4 Claims. (Cl. 128-284) The present invention relates to certain new anduseful structural and functional improvements in a diaper which,conjointly considered, serve to provide a diaper which is form-fittingand comfortable, is easily applicable and removable, and is otherwiseunique in construction for handy and practical usage.

More specifically, the invention has to do with a diaper of two-partconstruction wherein the parts coordinate their functions and provide adiaper which aptly serves the needs of both mother and child.

Another object of the invention is to structurally, functionally andotherwise improve upon similarly constructed and performing prior artdiapers and, in so doing, to provide a diaper which fulfills therequirements of manufacturers and acceptable needs of users.

Another object of the invention is to provide a simple, practical andeconomical diaper of two-part or sectional construction which promotesfast drying, easier and faster flushing, utilizes less space when hungon a clothesline for drying, embodies full and reliable absorbentproperties, and otherwise fulfills the requirements of all concerned.

Another object of the invention has to do with a twopart diaper whereinthe outer or main part constitutes the diaper proper, this being made upof two plies of appropriate material stitched together around threemarginal edges, the remaining edges being unattached so that said outerpart also has the function of a diaper bag.

Briefly summarized, a preferred embodiment of the invention ischaracterized by a main outer part, the diaper proper, and asupplemental inner part constituting a liner for the outer part, saidouter part being elongate and having inwardly curved concavelongitudinal edges defining a median form-fitting crotch portion andfront and back end portions, said inner part comprising an ovate flapsuperimposed upon and substantially covering the interior surface ofsaid outer part, said inner part having a pointed front end terminatingeven with the front end of said outer part, the back end of said innerpart being spaced in parallelism from and permanently attached to saidouter part, all other portions of said outer part being unattached andfree for handy use.

Then, too, novelty is predicated upon the construction stated whereinthe respective front and back end portions of the inner part areappreciably narrower than the corresponding front and back end portionsof the outer part, the median portion of said inner part being widerthan the cooperating median portion of the outer part, whereby thelengthwise convex edge portions thereof project or extend outwardly andbeyond the concave edge portion of the outer part.

Other objects, features and advantages will become more readily apparentfrom the following description and the accompanying sheet ofillustrative drawings.

In the drawings, wherein like numerals are employed to designate likeparts throughout the views:

Figure 1 is a perspective view of a diaper constructed in accordancewith the principles of the present invention showing the manner in whichthe components or parts of the diaper cooperate when applied to theinfant;

Figure 2 is a top plan view, or what may be called an interior or insideview, of the diaper illustrating the parts and their shape andarrangement;

Figure 3 is a reverse or bottom plan view of the same; and

Figure 4 is an enlarged central longitudinal sectional 2,705,010Patented Mar. 29, 1955 view taken on the plane of the line 4-4 of Figure2, looking in the direction of the arrows.

The aforementioned main outer part of component is denoted, generally,by the numeral 6 and it is, of course, of appropriate diaper material.It is of elongate form in plan when laid out flat. It is preferably oftwo-ply construction, and is actually formed from one piece of materialwhich is folded between its ends and upon itself into halves, with thehalves superimposed on each other and folded at 8. The two plies, asshown in Figure 4, are denoted by the numerals 10 and 12, respectively,and the marginal lengthwise edges are turned in and stitched together.figure that the ends or edges 14 and 16 are unattached. It follows thatthis main part serves not only as the diaper proper, but also, as adiaper bag. Whenever necessary or desired, this bag may be stuffed withextra wadding or throw-away absorbent material to increase thickness ofthe diaper. Or, the bag may be used for storage of other used diapersfor emergency and other requirements. In any event, the finished diaperhas straight-across transverse back and front edge portions. These arealso referred to as end portions, and the back end is denoted by thenumeral 18, while the front end is denoted by the numeral 20, the latterend being slightly narrower than the back end. The respectivelongitudinal edge portions are curved inwardly toward each other anddefine concave edges denoted by the numerals 22-22. The inner part,which is sometimes referred to also as a flap, is denoted by the numeral24. This part, which functions as a liner for the interior surface ofthe outer part and overlies the same in the manner shown in Figure 2, isof the special outline shown, that is, substantially ovate in outline.It is of such a length that the pointed end 26 extends to and terminatessubstantially flush with the edges 14 and 16. The other broader rear enddenoted at 28 is straight across and turned under and stitched orotherwise secured permanently, as at 30, to the diaper proper with theend 28 spaced from the adjacent fold 8. It will be noticed that onlythis one end portion of the flap or liner is attached. That is to say,the other edges are free so that the lining flap may be free to moveindependently of the outer part or diaper. It is further to be notedthat the intermediate, or median, portion of this inner part is widerthan the corresponding median portion of the outer part, whereby thecurvate convex edges 3232 actually extend beyond the concave edges 2224.It is desirable to cover as much of the interior surface of the completediaper as is possible when the diaper is applied, somewhat in the mannerillustrated in Figure 1. Although not absolutely necessary, the cornerportions 3434 are preferably blunt, as at 36-36. In practice, the cornerportions 3838 are attached to the corner portions 3434 by way of safetypins or the like 40, in the obvious mannershown in Figure 1, that is,when the diaper is applied to the infant. It is also to be noted thatthe inner part or liner is also made up of two plies 42- 42, as shown inFigure 4.

It will be evident that since the diaper illustrated has no snaps orequivalent elements, it is easier to dry, because the reinforcingnecessary with snaps would greatly add to the amount of time needed todry the diaper, as is obvious. Since diapers are usually wrung through awringer and hung on the clothesline for drying, it will be seen that thediaper herein illustrated lends itself to such laundering and hang-upand drying purposes. The diaper is simple and economical, and an obviousnovel contribution to the art. The inner part or liner serves to collectliquid and virtually all excrement, and allows the same to be dunked andpromotes easier flushing. These and other features and advantages willbe clear to the reader.

From the foregoing, the construction and operation of the device will bereadily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction shown and described, andaccordingly, all suitable modifications and equiva- It will be seen inthe same lents may be resorted to, falling within the scope of theappended claims.
